FRAPS recording makes my game laggy?

[tcco94]

Well ive switched from FSX to FS9 in April. I now run FS9 good settings and completly smooth. I havent made one of my youtube videos in a while on fs so I decide to do one today but I dont want it to be laggy because that makes the video less attractive.

So I boot up a test run with the cessna and takeoff....SMOOTH...then start the FRAPS and bam it starts to get laggy again? Once I stop the recording its fine.

Is there a way to stop this, ive tried changing the FRAPS frame rate to the same as my game but no luck...

Any advice or a good free screen recorder. I tried my camtasia studio and that was even more laggyer.

Thanks 8-)

Disk IO, Disk IO, Disk IO.
I dont know how that software caches out, but it might or might not affect the result

Disk IO

Could you explain that one?  :-?

Fraps writes video frames to the disk... 25 a second. that causes disk io (which fs needs for loading textures) and disk io causes processor load (that fs uses for flying).

I tryed a month after I posted this because noone helped me and it wasnt laggy and I got 2 new videos out of it.  :)

Thank you.  :)  Makes good sense.  

Is it possible on multi core processors to have FS on one core, and Fraps on another to alleviate some of this?
